Ensure all emails contain an unsubscribe link
Customize the unsubscribe page to offer alternative options
Create a suppression segment for unsubscribed users
Build an unsubscribe flow in Klaviyo to manage opt-outs properly
Monitor unsubscribe rates and analyze trends to improve retention

Step-by-Step Guide to Building a Compliant Klaviyo Unsubscribe Process
1. Ensure Every Email Contains an Unsubscribe Link
To comply with GDPR, CCPA, and CAN-SPAM laws, every email must have a visible unsubscribe link.
How to Add the Unsubscribe Link in Klaviyo:
Navigate to Email Templates in Klaviyo
Select a template to edit
In the footer section, insert:
css
CopyEdit
If you no longer want to receive emails from us, click here to unsubscribe: {unsubscribe_link}
Save and apply this template to all future emails
Klaviyo automatically tracks unsubscribed users and prevents further emails from being sent to them.
2. Customize the Unsubscribe Page
Instead of a one-click opt-out, brands can offer an alternative option to reduce unsubscribe rates.
How to Customize the Unsubscribe Page in Klaviyo:
Go to Account Settings > Email Settings
Click on Unsubscribe Page
Customize the message to:
"We’re sorry to see you go! Would you rather update your email preferences instead?"
Provide a Manage Preferences link that allows users to:
Reduce email frequency
Opt-in to specific content categories (e.g., Sales, Product Updates)
Switch to SMS notifications instead
This helps retain subscribers while allowing them to adjust preferences rather than completely opt out.
3. Create a Suppression Segment for Unsubscribed Users
To ensure unsubscribed users are not accidentally emailed, create a suppression segment in Klaviyo.
How to Build an Unsubscribed User Segment:
Navigate to Lists & Segments > Create Segment
Set the filter: Properties about someone > Unsubscribed from Email > is True
Save the segment as Unsubscribed Users
Klaviyo will automatically exclude this segment from all future email campaigns.
4. Build an Unsubscribe Flow in Klaviyo
A Klaviyo unsubscribe flow helps confirm user opt-outs and provides an opportunity to win them back.
Steps to Create an Unsubscribe Flow:
Go to Flows > Create Flow
Choose Create from Scratch
Set the trigger as:
Properties about someone > Unsubscribed from Email > is True
Add a conditional split:
If user unsubscribed within 7 days, send a confirmation email
If user unsubscribed from specific emails but not all, offer an email preference update
Add a final step to remove them from all marketing communications
This ensures unsubscribed users receive confirmation while also providing an opportunity to re-engage.
Best Practices for a Compliant Klaviyo Unsubscribe Process
1. Make It Easy to Unsubscribe
Never hide the unsubscribe link or require users to log in to opt out.
2. Offer a Preference Center Instead of Immediate Unsubscribe
Provide alternative options like:
Receiving fewer emails
Subscribing to only discounts and offers
Switching to SMS marketing
3. Comply with Global Email Laws
GDPR (Europe): Requires explicit consent and easy opt-out.
CAN-SPAM (U.S.): Must honor unsubscribe requests within 10 days.
CCPA (California): Requires businesses to delete user data upon request.
4. Monitor Unsubscribe Rates & Adjust Your Email Strategy
Track unsubscribe trends in Klaviyo by going to Analytics > List Growth.
If unsubscribe rates exceed 0.5% per campaign, review:
Email frequency
Content relevance
Subject line engagement
5. Ensure SMS Compliance for Opt-Outs
SMS must include a “Reply STOP to opt-out” message.
Suppress opted-out SMS subscribers in the SMS Suppression List.
Common Mistakes That Can Lead to Compliance Issues
🚫 Forcing Users to Log In to Unsubscribe – Users should be able to unsubscribe with one click.
🚫 Not Honoring Unsubscribe Requests Quickly – GDPR and CAN-SPAM require that opt-outs are processed within 10 days.
🚫 Hiding the Unsubscribe Link – Making it difficult to unsubscribe can lead to spam complaints.
🚫 Failing to Segment Unsubscribed Users – Always create a suppression segment to prevent accidental emails.
🚫 Not Offering Alternative Subscription Options – A preference center can reduce unsubscribes by offering lower email frequency or SMS options.
Conclusion
A compliant Klaviyo unsubscribe process helps brands avoid legal fines, improve email deliverability, and retain subscribers more effectively. By following best practices, such as creating a suppression list, preference center, and an unsubscribe flow, brands can reduce unsubscribes while staying compliant.
